To all whom it may concern:

Be it known that I, FaANors LINCOLN YOUNG, a citizen of the United States, residing at New York city, in the county and State of New York, have invented certain new and useful Improvements in Sound- Records, of which the following is a specification.

' My present invention relates to an improved sound-record, the features and advantages of which will be apparent from an vibrations impressed upon them, and these are so minute that it would require minute inspection, for most people with the aid of a magnifying glass, to determine which is the first playing groove of the record. In the same way, the last playing groove comes wherever the particular selection happens to end; and again it is only minutely, not plainly visible. My invention comprises a plainly or largely visible mark or indication on the record itself of the first and last playing or sounding grooves of the record, this being in distinction from the merely minutely visible conformation of the soundgroove itself. With such a record, it for the first time becomes practicable to limit the contact between the reproducer and the record to the actual playing portion only, thereby cutting out the annoying beginning and ending blank grooves where there is nothing to be heard except the scratch of the needle. Furthermore whereas there have been proposed in the art a great many automatic starting, stopping and recordrepeating devices, they have had to be set either without reference at all to the beginning or ending of the actual playing portion of the record, or by guess-work or by playing trials of the record. This haphazard ness is eliminated for users of the records of my invention who can now instantly adjust with accuracy the automatic stop and repeat devices to confine the given record within its playing limits.

In the drawing, the darkened grooves 3 and 5 are supposed to mark the confines of the playing portion of the record. These may be the actual first and last playing grooves, or preferably the grooves outside them. If the record be black, these specific grooves and perhaps the adjacent non-playmg grooves or ridges will be given in whole or in part a distinctive coloration such as white or red. The coloration or marking may be superficial or incorporated in any way with the record, and for example may underlie a transparent or translucent surface or coating of the record. The marking material applied to or incorporated with the record may be self-luminous or phosphorescent so as to be all the more certainly visible even in the absence of a fair light. The distinctive colorations or markings may be applied to the grooves, or the tops of the ridges, or both.

My invention further comprises a record having a plainly or largely visible mark thereon adapted to be aimed at in adjusting the stylus to the record. For this purpose any one of the beginning and ending grooves, preferably not the very first or last may be marked so as to be plainly visible. This groove will be aimed at in adjusting the stylus to the record, either merely for starting the playing of the record in the ordinary manner, or for adjusting the automatic stop or record-repeat device; and will obviate a largely prevalent difiic-ulty experienced by persons playing phonographs which is the liability to unintentionally place the stylus on the bare or plain margins 6 of the record due to the fact that the demarcation between said margins and the record-grooves is not plainly visible especially when the record is in playing position in the instrument.

These and other advantages of my invention will be apparent to users of instruments FRANCIS LINCOLN YOUNG, or NEW ORK, N. YL, ASSIGNOR To THE AEOIliAN COMPANY,

and non-playing portions for the travel of the stylus therein and demarcating means extending around the record substantially between the annular zones occupied by said playing and non-playing portions of the groove and in the general direction of such groove whereby said demarcating means will be readily visible while the record is in operation.

In testimony whereof, I have signed my 10 name to this specification, this 27th day of June, 1916.

FRANCIS LINCOLN YOUNG.
